【摘要】：為了降低固體氧化物燃料電池在制備和工作過程中產(chǎn)生的熱應(yīng)力,提高電池的電化學(xué)性能,在電池中引入功能梯度層可以有效減小電池各層之間材料參數(shù)的差異,從而緩解各層之間的熱失配應(yīng)力。本研究將陽極功能層引入燃料電池中,通過陽極功能層子層數(shù)目和非線性梯度成分指數(shù)n控制各子層材料屬性的變化情況,研究了燃料電池在800℃下的熱應(yīng)力分布。結(jié)果表明:選取適當(dāng)?shù)闹笖?shù)n和陽極功能層的分層數(shù)目可以明顯降低陽極層的最大拉應(yīng)力和電解質(zhì)層的最大壓應(yīng)力。
[Abstract]:In order to reduce the thermal stress in the preparation and operation of solid oxide fuel cell and improve the electrochemical performance of the battery, the difference of material parameters between the layers can be effectively reduced by introducing the functionally gradient layer into the battery. Thus, the thermal mismatch stress between the layers is alleviated. In this study, the anodic functional layer was introduced into the fuel cell, and the thermal stress distribution of the fuel cell at 800 鈩，
